Facebook not showing image with link

[freakhouse]

My site is redlinemusicgear.com   I'm using prestashop 1.5.5

I've tried posting a link to my site on facebook and an "image not found" comes up. My understanding from looking at facebook debugger and on other posts is that I need to add or modify a meta tag to do this. It looks like from the debuger that the meta tag is already there, just pointing to the image not found jpg on my site. Where do I change this code? I've seen references to the SEO page in Back Office and I don't see anywhere to change this when I I look at index.php from there.  I've also seen stuff about modifying a database file.  Any ideas?

 

thanks!

your website doesn't use all necessary open graph tags.

 

can you check header.tpl file (located in your theme directory) for og:image tag? i suppose that it is defined there

I've looked in that file and I don't see any reference to this link http://redlinemusicgear.com/img/p/en-default-large_default.jpg

 

that link  is what facebook shows it's is pulling on it debugger page. I've temporarily changed the unavailable pic to a logo for my site.  

 

I'm guessing this is referenced somewhere else. But where?

so, if you haven't got code of og:image in header.tpl maybe you use some open graph tags module?

this is a part of your website:

 

as you can see it is defined in <meta> section, it mean that it is probably defined in some of the modules that you use

you should go to modules > positions

search for "displayHeader" and check last module (or 2-3 last modules) on "displayHeader" list
